Question

when 2.941 g of mercuric compound is vaporized in a 1 L bulb at 680 K, the pressure is 458 mm. The molecular weight of the compound is

Answer 1

Answer:

294.1 g

Explanation:

Using PV=nRT

1*458/760 = n*0.0821*680

The closest value of n is about 0.01.

n = given mass / molecular mass

Molecular mass = 2.941/0.01 = Approximately 294.1 g.

Hope that helps.
